3 Description
The DRV5015 is a low-voltage digital-latch Hall effect
sensor designed for high-speed and high-temperature
motor applications. Operating from a 2.5-V to 5.5-V
power supply, the device senses magnetic flux
density and presents a digital output based on
predefined magnetic thresholds.
Alternating north and south magnetic poles are
required to toggle the output and integrated
hysteresis provides robust switching.
The device is offered in two magnetic threshold
options and an inverted output option. The high
magnetic sensitivity provides flexibility in low-cost
magnet selection and component placement.
The device performs consistently across a wide
ambient temperature range of –40°C to +125°C.
